當然有了。但是是以nanorod為主,講光學性質(zhì)的。王建方老師還算是小牛。在大牛Murphy等人的基礎(chǔ)上,對金納米棒的控制做得是爐火純青,JACS也發(fā)了一些。 不必多說,上文獻: Plasmon—molecule interactions Nano Today (2010)5, 494—505 Wang Jianfang et al. Abstract: Interactions between the plasmons of noble metal nanocrystals and organic molecules can give rise to a number of interesting phenomena, which have recently received enormous interests and will lead to a wide range of technological applications. The interac-tion behavior is strongly dependent on the electronic structures of organic molecules. Here we review our recent work on the three types of interactions between Au nanocrystals and organic molecules. The first is the interaction between plasmons and molecules without absorption, which leads to refractive index change-based plasmonic sensing. The refractive index-induced plasmon resonance shifts are found to be strongly dependent on the plasmonic properties of Au nanocrystals. The second is the plasmonic—molecular resonance coupling, where molecules exhibit strong light absorption around the plasmon resonance energies. The strong resonance coupling gives hybridized states and anti-crossing behaviors. The third occurs when molecules possess both absorption and fluorescence emission around the plasmon energies. The flu-orescence intensities of fluorophores can be enhanced remarkably in the presence of Au nanocrystals. |
